green algae (Chlorophyta), red algae (Rhodophyta) and brown algae (Phaeophyta) depending on their nutrient and chemical composition (Dawczynski et al., 2007). In addition, the seaweed industry uses tones of wet seaweeds annually, either from the wild or from cultivated crop (Dhargalkar and Verlecar, 2009). Seaweeds or marine macroalgae are potential renewable resource in the marine environment and known to be extremely rich source of bioactive compounds (Chandini et al., 2008). Therefore, algae can
Hawaiian algae published on the UH website, I identified the algae as of the genus Padina, however I am not quite sure which species it is. The most common species of Padina in Hawaii are the P. australis and P. japonica, and is sometimes referred to as "peacock's tail" because of its fan-like shape. Padina is a member of the class phaeophyceae, which is a class of brown algae. The peacock's tail alga is not harmful when eaten, however it can be dangerous when walking across rock, as the algae can get
same between two red algae, or two green algae. In this lab a red, green and brown algae will be used to extract the photosynthetic pigments from. We will also be extracting the photosynthetic pigments from Coleus sp., which is a red land plant leaf and, and compare the accessory pigments of this to the red algae. Methods and Materials We used two different kinds of red algae for this experiment. The first was Polysiphonia sp. and the second Porphyra sp. The green algae were Entreromorpha
Introduction Fossil records indicate life has existed on this planet for at least 3.8 billion years. Most species that have ever existed are now extinct, yet the diversity of life on Earth is still so tremendous and complex scientists estimate there are 10-100 million species yet to be documented. Those that have been documented, have been categorized it into three domains, six kingdoms, twenty-nine phyla, and countless more subdivisions. Seemingly in spite of this diversity, a common ancestry unites
The Brown Pigment The brown colour of brown algae is due to presence of green pigment (chlorophyll a and c) and the brown fu-coxanthine. The seaweeds which live in deep water absorb different wavelength of light due to the presence of these different types of pigments and manufacture their food by the process of photosynthesis. Laminarin, a unique type of starch, is produced in brown algae. Examples of Brown Seaweeds 1. Kelp Sea bamboo (Ecklonia maxima), the spilt fan kelp (Laminaria pallida)
phlorotannin derivatives with special bioactivities including ACE inhibitory activity. Ethanol enhances the extraction of phlorotannins specially dieckol from the brown seaweed E. cava. By contrast, in this study phloroglucinol derivative dieckol exhibited the strongest activity against ACE. With the results of this study we can suggest that the brown seaweed E. cava could be used in development of promising and potential functional food products. Moreover, it is expected that these findings will contribute
My Aquarium The place I decided to do my paper on is located in the living room of my family’s house. It is a one hundred gallon aquarium. The reason I chose this as the topic of my paper is that all kingdoms are present except for Plantae in it and it is its own ecosystem. Before I go in detail about the organisms in the aquarium, I would like to mention the accessories that make this aquarium a stable environment and allow the organisms to grow happily. The temperature needs to mimic
Diatoms are even the most common type of life in the ocean. This organism is similar to plants because of the photosynthetic qualities they posses. Diatoms use photosynthesis to absorb light, yet the pigment they possess is brown. Such aspects relate diatoms to brown algae. For this reason, scientists typically place them in the plant kingdom but others state today they are in the kingdom Protista. They are not restricted to aquatic environments, such organisms can be found all over the world even
which causes a dense growth of plant life. Eutrophication arises from the oversupply of nutrients, which induces explosive growth of plants and algae which, when such organisms die, they consume the oxygen in the body of water, thereby creating the state of hypoxia (deficiency in the amount of oxygen reaching the tissues) Mechanism of Eutrophication When algae die, they decompose and the nutrients contained in that organic matter are converted into inorganic form by microorganisms. This decomposition
Metropolitan University in 2013. Written works on marine research conducted by Earle includes books such as Seaweeds of the Gulf of Mexico and The Panamic Biota: Some Observations Prior to a Sea-Level Canal, regarding the protection and preservation of algae and marine life within the pacific. Seaweeds of the Gulf of Mexico outlines the importance of protozoa in the gulf of Mexico and the lengths at which they may be protected. As Quoted from the text, “Our understanding of algal phylogeny has dramatically

We can see how different wavelengths of light affect photosynthesis by looking at action spectra. An action spectrum relates the rate of photosynthesis to the wavelength of light being received by a plant. For green plants, including algae, the action spectrum shows that
completely different organisms, microscopic green or blue-green algae and colorless fungal threads called hyphae” (Hale, 1969). It is interesting to see that these two organisms seem to live harmoniously with each other in symbiosis. What also makes this plant so different from all others is that a new plant body, referred to as the thallus, is formed. “This new composite organism behaves as a single independent plant, the green algae manufacturing sugars by photosynthesis and the fungus living off
Environmental problems happen everywhere around the world. Something similar happened in the Gray Area. The Gray Area is a region that is surrounded by mountains and rivers. The Missterssipi river, the Rafta river, and the Fo river are the rivers that currently exist in the Gray Area. These three rivers flow down and congregate to the Gray Bay. There are many tourist attractions in the Gray Area like, the golf course. Recently, fish have been dying and have been washing on to the shores of the Gray
for over 200 million years. Over 2500 species of coral have been identified 1000 of which are reef building hard coral. Reefs are actually limestone structures produced by small animals called coral polyps. These polyps contain unicellular plants (algae) called zooxanthellae in their tissue. They have a symbiotic relationship which means, "living together." During the day the zooxanthellae rise to the surface of the animal and produce food by photosynthesis. At night the polyp extends a stinging,
Red is a algae bloom that releases toxins into the ocean and releases horrid smells that can leave you with respiratory problems like hacking horribly, minor cough , or asthma in worse cases. The algae bloom releases toxins when its in a high concentrated state into the ocean that the shellfish take in but they don’t die. Instead they concentrate all of it into their body’s in a small space and if a human eats the shellfish the human has a huge chance of dying because of the toxin. The algae bloom also
Numerous breeding strategies exist, but each is targeted at maximizing the reproduction of species. All members of the shrimp colony are the offspring of one female. She is the queen and the only one to produce eggs. Brown surgeonfish wait until the light the light fades and then the females in the group release their eggs while the quickest males in the group try to fertilize them. The Banded pipe fish find their partner and create a bond before they entwine their bodies
Diverrsity of Plants Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes and ferns require free water so that sperm can swim
interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life and its characteristics. These characteristics include cellular
on the North side of the tree. I think this will happen because, the south side of the tree receives the most sunlight. The heat from this sunlight would dry out the Pleurococcus, which would cause it to dry out, and die. As Pleurococcus is an algae, it photosynthesises. This means it needs water as is shown in the photosynthesis equation below. Sunlight [IMAGE]Water + Carbon Dioxide Oxygen + Glucose (aq) (g) (g) (s) Sunlight [IMAGE]6H20 + 6CO2 6O2 + C6H12O6 (aq)
